Why the Plane was Invented and Some Historical Tidbits

Photo Credit: pixabay.com You may wonder why the plane was invented? Due to man’s desire to discover new methods of transportation and the desire to travel long distances without the complications of terrain as well as to travel in the shortest time possible, the plane was then created. What was the first flight in history? While many believe that the airplane was invented by the Wright brothers in Kitty Hawk, N.C., it was said that the first man to fly was New Zealander Richard Pearse in 1902, eight months before the Wright brothers first flew. Pearse, according to witnesses, flew a length of 50 to 400 yards in a heavier-than-air machine. Pearse’s aircraft was the first to use proper ailerons, which allowed the wings to warp and turn the aircraft. Though many credit the invention of airplanes to the Wright brothers, Richard Pearse never reported his inventions because he didn’t know there was any interest in flying. However, the Wright brothers were the first flyers to be officially recorded and the first to have also patented their invention. Though the Wright brothers tested many gliders in the early 1900s, none of them counted as an actual aircraft, and the brothers didn’t achieve flight until late 1903 with their first plane, the Flyer I. The craft weighed over 600 pounds, and Orville Wright was the first pilot, which was decided through a toss coin. The craft remained airborne for 12 seconds and traveled a little over 120 feet. To zoom in on the aviation history of the Philippines, here is a timeline of the Philippine Airline Industry: The government created an...

HRS for the Win, Again!

The most anticipated and prestigious culinary competition in Mindanao is back in Davao City to showcase the talents, skills, and creativity of Davaoeños. The 2017 Davao Culinary Cup (DCC), powered by Philippine Culinary Cup (PCC), held its 3rd Culinary Competition last  August 29 to 31, 2017 at the Atrium of SM Lanang Premier. “It’s a competition where we actually want to introduce the standards here in Davao and of course, learn from people in Davao,”  said Chef James Antolin of LTB Manila and Competition Director of the event, when he was asked about the main objective of the event. 228 aspiring chefs from different culinary colleges,   establishments, and institutions all over Mindanao competed in the region.  This year,  6 participants from Hotel and Restaurant Services( HRS) of Asian and International School of Aeronautics and Technology vied in the Savory Category; Young Chef’s Team Category, Pasta Category, and Local Fish or Seafood Category. Despite the heightened pressure due to the changes in the rules on preparation time and quantity of servings, participants valiantly and keenly prepared their dishes. “Our one-week preparation was rigid because we had to teach the basics,” exclaimed Chef Ariel de Leon, HRS Instructor, and mentor “ Even though most of the representatives were first timers, we trust our students that they will do their best,” he added. Indeed, the efforts were all worth it! The AISAT HRS Department celebrated as Joshua San Pedro and Jose Carlos San Pedro batted the Bronze medal in the Young Chef’s Team Category with their dishes Prawn Thermidor and Prosciutto Stuffed Chicken with Mushroom and crusted Cashew Nuts. Participants really made...

What is an Airfoil in Aviation?

Photo Credit: pixabay.com You may or may not have heard what is an airfoil on an airplane. What is an airfoil and how does it work?  An airfoil is the shape of the aircraft’s wing, blade (of a propeller, rotor, or turbine). It is the term used to describe the cross-sectional shape of an object that, when moved through a fluid such as air, creates an aerodynamic force. Airfoils are employed on aircraft as wings to produce lift or as propeller blades to produce thrust. Both these forces are produce perpendicular to the air flow. Drag is a consequence of the production of lift/thrust and acts parallel to the airflow. Other airfoil surfaces include tailplanes, fins, winglets, and helicopter rotor blades. Control surfaces are shaped to contribute to the overall aerofoil section of the wing or empennage The basic principle behind an aerofoil is described by Bernoulli’s theorem. Basically, this states that total pressure is equal to static pressure (due to the weight of air above) plus dynamic pressure (due to the motion of air). Air that travels over the top surface of the aerofoil has to travel faster and thus gains dynamic pressure. The subsequent loss of static pressure creates a pressure difference between the upper and lower surfaces that is called the lift and opposes the weight of an aircraft (or thrust that opposes drag). As the angle of attack (the angle between the chord line and relative air flow) is increased, more lift is created. Once the critical angle of attack is reached (generally around 14 degrees) the aerofoil will stall. According to Dynamic Flight (2002), several terms are used to describe what...

Are Solar Planes the Future of Flight?

Photo Credit: pixabay.com Between years 2015 and 2016, Solar Impulse 2, the first flying solar aircraft, completed a circumnavigation of the Earth. This may be quite an achievement in aviation since aircrafts are mostly being propelled by fuel-powered engines. This may also be an environmental achievement, as it only uses solar power to make airplanes fly, as opposed to fuel which would bring about a heavy amount of carbon emissions in the atmosphere. Now that Solar Impulse 2 has flown and completed a turn around the Earth, are solar planes the future of flight? How does a solar-powered airplane work anyway? Here’s a preview of how it works, from revolvy.com: a Solar cell converts sunlight into electricity, either for direct power or temporary storage. The power output of solar cells is small, even when many are connected together, which limits their use and is also expensive. However, their use of freely available sunlight makes them attractive for high-altitude, long-endurance applications. For endurance flights, keeping the craft in the air all night typically requires a backup storage system, which supplies power during the hours of darkness and recharges during the day. Now back to the journey of the first flying solar aircraft. Solar Impulse 2’s journey to circumnavigate the Earth took more than a year, 505 days to be exact, to fly 26,000 miles (42,000 km) at an average speed of about 45 mph (70 kph). Despite its relatively slow speed and relatively low altitude, Swiss pilots Bertrand Piccard and Andre Borschberg successfully landed the Solar Impulse 2 aircraft in Abu Dhabi on July 26, 2016, after flying around the world using...

CAAP Meets with Davao Airport Concessionaires

CAAP Meets with Davao Airport Concessionaires The Civil Aviation Authority of the Philippines through the Corplan Business Unit Staffs, headed by Atty. Jerry Lerum conducted a meeting and orientation with the concession applicants at the CAAP Davao office on August 8, 2017. All the existing concessionaires in the Davao International Airport Terminal were invited to hear the presentation and proposal of the CAAP regarding the implementation of a more organized leasing arrangement between the CAAP and concessionaires. In line with this, CAAP is set to release a manual on lease agreements with concessionaires, which many will find refreshing, especially when longer lease terms are now a possibility. Most of the existing concessionaires have been relying on monthly rental agreements with the CAAP as the renewed contract for 2017 have not been released by the central office. This place many business owners in an uncertain position on whether to invest in their businesses for fear of non-renewal of contracts.     The Corplan Business Unit staff presented how they envision the Davao Airport to be a more pleasant terminal for visitors by zoning business activities as well as by increasing foot traffic in areas that do not get as much patronage due to the location of stalls. Some of the ideas that were brought up were the construction of commercial units in the parking area, to host convenient outlets or even refreshment stalls to cater to people who are waiting for passengers to arrive. The front portion of the terminal building will also be leased to ticketing offices for the convenience of passengers. The team also proposed to zone the...

How to Prepare for a Long Flight

Photo Credit: pixabay.com A long flight, just like any other means of transportation that takes a long while, requires preparations so that it would go on smoothly. Some of the tips how to prepare for a long flight is enumerated below: 1. Prepare a flight plan Flight planning is the process describing a proposed aircraft flight. It involves fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air traffic control requirements, to minimise the risk of midair collision. How to prepare a flight plan? Flight planners normally wish to minimise flight cost through the appropriate choice of route, height, and speed, and by loading the minimum necessary fuel on board. These things are accomplished through looking at a flight preparation checklist. 2. Destination You have to make sure that there is enough available fuel, especially if it is a long flight. By knowing where you will go, ensure then that airports will be open and that the weather permits flight. 3. Route When you plan a route for your flight, choose a way that will allow you to fly at a safe optimum altitude for your aircraft. Also, be aware of some temporary flight restrictions when you plan your route. 4. Weather The weather is one of the most important factors when you prepare for a long flight. Get an updated weather briefing from reliable sources such as the flight service station or other reliable weather stations or sites. 5. Altitude and cruise profile If you want to fly high enough to maintain the required clearance from terrain and obstacles, you’ll want to consider the ability of...

What is Aircraft Maintenance?

Photo Credit: pixabay.com Pilots and other flight crews are the workers you might immediately think about when you think about airplanes since they are the ones who are the most visible to passengers. However, those people who work behind-the-scenes are the ones who have a very important role in keeping the plane safe and efficient. These skilled workers are called aircraft maintenance technicians or licensed aircraft maintenance technicians if they have passed the licensure exam which enables them to do their work professionally. So what is aircraft maintenance? What does an aircraft maintenance technician do? Is there such a thing as an aircraft maintenance technician course? The next few paragraphs shall attempt to answer these questions for you. First, what is aircraft maintenance? It is the system of periodically repairing, replacing, and maintaining aircraft parts and components as well as the performance of maintenance and functional checks on various aircraft systems to ensure a smooth, safe and efficient flight. This typically includes assembling and installing electrical, plumbing, mechanical, hydraulic, and structural components and accessories through using appropriate tools; checking for any corrosion, distortion, or any defects in the plane’s body, such as the fuselage, wings, and tail, using appropriate inspection equipment; examining and inspecting several aircraft components, such as landing gear and hydraulic systems; trimming and shaping replacement body sections (if any) to fit its specific size; inspecting airframes for possible wear and tear; inspecting completed work to certify that the maintenance conducted on the aircraft meets the safety and operational standards; and servicing and maintaining aircraft and related apparatus by performing activities such as flushing crankcases, cleaning screens,...

All About the Forces of Flight

Photo Credit: pixabay.com Ever wonder what keeps the plane up in the sky? The four forces of flight are thrust, lift, drag and weight. So, what are the four forces of flight and what do they do? Let us enumerate each of this for better understanding. The first force, thrust, is the force that moves the airplane forward, of which the plane’s engine is responsible. The high speed from the airplane’s thrust makes rapid air flow over the wings, which throw the air down toward the ground. From this, an upward force is generated, Called lift which is another force of flight. Lift overcomes the plane’s weight and holds it in the sky. Simply put, the lift pushes the airplane up; wings make lift by changing the direction and pressure of the air that crashes into them as the engines shoot them through the sky. The lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down; it is this difference in pressure that enables the plane to fly. Pressure can be reduced on a wing’s surface by making the air move over it more quickly. For additional information, the wings of a plane are shaped like a curve so that the air moves more quickly over the top of the wing, resulting in an upward push on the wing. Remember, it’s the engines that move a plane forward (i.e., thrust), but it’s the wings move it upward (i.e., lift). Another force, called drag, slows the airplane. For a relatable picture, drag is what you feel when you walk against a...

Preparing For Your Flight Training

Photo Credit: pixabay.com When choosing a flight school, it helps if you know why you want to go into the field of aviation. Why do you want to learn to fly? Do you want to fly only as a hobby, or are you do you want to make flying as a career? Do you want to train full time or part time? These are some of the questions that you should answer before you start considering flight training. So, how to choose a flight training school? How to prepare for a flight school? Here are three things to consider when selecting a flight training school. Quality Education quality is the most important factor when choosing a flying school. The quality of what you will learn in your school will reflect on the quality of your output when you will be sent out to the real world once you graduate. More importantly, flying a plane is a matter of life and death not only for you but for your passengers. Hence, you must be able to have a superior knowledge in the field. The excellence and the integrity of your teachers and the quality of the flying school’s curriculum is a must-have. Location Costs can be maximized when the location of your chosen flight training school is one that is close to your residence. Another consideration in choosing a school is that it is easily accessible, where you can easily go to a mall, a store, a bank or a clean and safe eatery. Moreover, since you will spend most of your time in school more than any other place,...

Things You Need to Know About Air Traffic and Safety Navigation

Photo Credit: pexels.com Ever wondered how airplanes don’t seem to run into each other? Or why is it that every time you ride a plane, there is no other plane around? There is an air traffic and safety navigation system in place which is called an air traffic control system, filled with somewhat complicated air traffic equipment that only trained individuals are allowed to manipulate. Air traffic control or ATC is a service provided by trained personnel who direct aircraft on the ground and provide advisory services to active aircraft. The primary purpose of ATC is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots, such as the weather and its destination’s airport information. To prevent collisions, ATC enforces traffic separation rules, which ensure that each aircraft maintains a minimum amount of empty space around it at all times. Many aircraft also have collision avoidance systems, which provide additional safety by warning pilots when other aircraft get too close. The primary method of controlling the immediate airport environment is through visual observation from the airport control tower. The control tower is a tall, windowed structure located on the airport grounds.  Surveillance displays are also available to controllers at larger airports to assist with controlling air traffic. Controllers may use a radar system called secondary surveillance radar for airborne traffic approaching and departing. These displays include a map of the area, the position of various aircraft, and data tags that include aircraft identification, speed, altitude, and other information described in local procedures. In adverse weather conditions, the tower controllers may also use surface movement radar (SMR), surface movement guidance and control...

What is Aerodynamics?

Photo Credit: pexels.com Aerodynamics feels like such a big word but what is aerodynamics, really? And how can aerodynamics affect flight?  First things first, let’s define it. Aerodynamics, from the Greek words aerios, which means “concerning the air,” and dynamis, which means “force” is the way air moves around things. Aerodynamics in planes is explained through the forces surrounding it and its body structure as well. Read further and be enlightened! Lift When an airplane moves through the air, its weight causes the wings to push down. Because of this action, an opposite reaction occurs as air below the wings pushes them up. Pilots can adjust a wing’s angle to control how much air the wings push down; as wings push more air down, lift occurs. Airspeed, Ground Speed, and Wind Speed For lift to occur, a motion must exist between the wing and the air. The square of the velocity between the air and a wing determines its lift; the faster a plane moves through the air, the greater its lift. The Wright brothers designed their plane to fly when airspeed reached 35 mph. Because a 25 mph headwind was blowing into the plane as it traveled down the runway, it was able to lift off when its ground speed was only 10 mph. That’s because the 25 mph wind speed combined with the 10 mph ground speed to create an actual airspeed of 35 mph. Drag Drag, another aerodynamic force, opposes the aircraft’s motion through the air and attempts to slow it down. Induced drag near a plane’s wingtips also occurs because of the difference in pressure between...

What makes airplanes fly?

Photo Credit: pexels.com Ever wondered how can airplanes fly? Or are you just one of those who just takes it for granted, as long as you arrive at your destination? Nevertheless, it is very interesting to know the intricacies of what makes airplanes fly. You may have observed several planes taking off or landing, and the first thing that you’ll have noticed is the engine noise.  You might think that engines responsible for making planes fly, but you’re wrong. As you can see, paper planes and birds can fly without this stuff. A plane’s engine is designed to move it forward at a high speed which only helps to make it fly but is not totally responsible for keeping it up in the air. So really, what makes airplanes fly? Four forces keep an airplane in the sky. These are thrust, lift, drag and weight (or gravity). Thrust is the force that moves the airplane forward, care of the plane’s engine. This high speed from the thrust of the plane makes rapid air flow over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. Simply put, the lift pushes the airplane up. Wings make lift by changing the direction and pressure of the air that crashes into them as the engines shoot them through the sky. Remember, it’s the engines that move a plane forward, but the wings move it upward. The lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is...

What are the Parts of an Airplane?

Photo Credit: pexels.com You may have just considered a plane as a means of transportation, but have you ever wondered what are the parts of an airplane? Read on to satisfy your curiosity on the different parts of an aircraft and their purposes as well. The body of the airplane, formally called fuselage, holds all of the pieces together which serves as a connecting point for all the airplane parts. This is where you will find the passengers and cargo. The wings are the primary lifting surfaces for the aircraft which produces aerodynamic force for the plane to go up. The airflow over the wing is what generates the vast majority of lifting force necessary for flight. It works to help in balancing and improving the aircraft’s stability when flying. The power plant or the engine generates the power or thrust for the aircraft which is a major component that allows the aircraft to move. The type of engine varies in accordance with the plane’s size. There are different types of engines but the two types that are widely used are turbofan and turbojet. The landing gear allows the aircraft to take-off, land, and taxi, and also provides shock absorbers to enable smooth landing and take-off. The empennage consists of the vertical stabilizer (the “tail” of the airplane) and the horizontal stabilizer or stabilator. It has the following sub-parts: The rudder is a movable piece of the vertical stabilizer that allows the airplane to turn left or right; it is connected to the foot pedals in the cockpit of the airplane The elevator is located on the rear part of the horizontal stabilizer. It...

All about landing safely

Photo Credit: pexels.com We know that planes go down upon finishing a flight, but the proper term for this is called an airplane landing. An airplane landing is the last part of a flight, where an aircraft returns to the ground. Aircraft usually land at an airport on a firm runway which is generally made of asphalt concrete, concrete, gravel or grass. Some aircraft are equipped with pontoons (a.k.a. floatplanes) or with a boat hull-shaped fuselage (a flying boat) which enables them to land on water. Sometimes it uses skis to land on snow or ice. To land, the pilot reduces the airspeed and the rate of descent to allow for a gentle touchdown. Landing is accomplished by slowing down and descending to the runway. The plane’s slowing down is accomplished by reducing thrust and/or inducing a greater amount of drag using flaps, landing gears or speed brakes. Are you curious about how to land? Here are all about landing safely from Mirror Online News UK: The captain usually sits in the left seat where the majority of instruments are. Seatbelts should be fastened and wear the shoulder harness if there is one. Level the aircraft. If the plane is noticeably ascending, descending, or turning, gently bring the plane into a level. Look for the altitude indicator. Sometimes called the artificial horizon, it consists of a miniature set of “wings” and a picture of the horizon. Turn on autopilot. Turn it on by pushing buttons labeled “AUTOPILOT” or “AUTO FLIGHT,” “AFS” or “AP” or similar. Call for help on the radio. Look for a hand-held microphone, which is normally to...

Why is it safer to travel by air than by land?

Photo Credit: pixabay.com Why is it safer to travel by air than by land? From safe air travel tips to air travel safety briefings during flights, it could be easily deduced that it is indeed a safer mode of transportation, despite being thousands of feet in the air. Still not convinced? Here are some reasons to persuade you to think otherwise. 1. Airplane design The world’s commercial airliners have accumulated an estimated number of one billion flight hours which provided the airline industry with records and a steady stream of information that is used to constantly improve the design of airplanes and engines. Today, manufacturers know what happens in the real flight scenario, which prompts refinements that may make a genuine difference in safety and design. 2. Airline technology Compared with your car’s latest technology, airline technology makes motor vehicles look like vessels from the Stone Age in comparison as technology on airplanes controls almost the entire flight. For instance, planes can detect turbulence and can predict the general behavior of the turbulence. Also, runway safety technology communicates between planes to warn pilots if there may be another incoming plane. These technological improvements control all aspects of flying and the responsibility of a pilot to steer a plane is almost obsolete. Most planes today feature electronic controls that have replaced outdated mechanical controls.  3. Rigorous pilot training Pilots go through rigorous training and certification processes. Many pilots are retired members of the Air Force plus, one must go to flight school and receive a pilot’s license. Most airline companies also require pilots to attend at least 2 years of college.  4....
